MINERS'LAMR' Specification of Letters Batent. Patented Dec, 16, 1919,

Application filed December 2, 1918. Serial No. 264,895.

To all whom it may concern:

Be it known that I, WILLIAM Hosso, a

. citizen of the United States of America, and

resident of Nefis, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Miners Lamps, of which the following is a specification.

This invention relates broadly to acetylene gas lamps, and more specifically to a gas lamp of that type commonly employed by miners.

The primary object of the invention is to provide an acetylene gas lamp embodying two separate carbid containers or gas genera-ting tanks designed for independent and consequently alternate use, and including means whereby the removal of either of said containers for recharging may be accomplished while gas from the other container is utilized for furnishing light.v

A further object is to provide a miners gas lamp which is simple in construction,

which has its parts compactly arranged and readily accessible for cleaning, which is' light in weight, and which is particularly efficient in operation.

A further object is to provide a lamp of the character mentioned having a single adjustable valve whereby the flow of the water to and the passage of gas from both carbid containers is controlled. 7

With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elementswhich will hereinafter be fully describechreference being had. to the accompanying drawings, in which 7 Figure l is a view of the invention partly in rear elevation and partly in vertical see- Fig. '2 is a side elevation: of the-same;

Fig. 3 is a horizontal section on line 3 3, Fig. 1; a r

Fig. 4: isa front elevation of the reflector;

Fig. 5 is an enlargedsection on line 5+5, Fig. 3; and

Figs. 6 and 7 are sections taken on lines 66 and 77, respectively of Fig. 15.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views-:-

I, 1 indicates a water reservoir having a filler opening in the top there f provided with a removable cap or cover 2 which'is preferably hinged to'said reservoir as shown ports 4 together constitute gas generating atu3 in Figs. 1 and 2. Rigidly carried by the bottom 1 of the reservoir are two depending cylindrical supports 4. Each of said supports has its lower end screw threaded for receiving thereon the upper threaded end of a cylindrical cup or carbid container .5. Each of saidcups 5 has an annular terminal flange 6 adapted to seat against a. corresponding collar dike flange 7 carried by its support 4 above the screw threads of the latter and at a suitably spaced distance from the bottom of the water reservoir 1.

Said cups or containers 5 and theirv suptanks. -;Either of said containers may be readily detached, as for replenishment With carbid, while the other functions tofurnish gas. 7

Soldered or otherwise suitably attached to the under side of the bottom 1 of the reservoir 1 between the two containers 5 and occupying a position above the flanges 7 .of the latter is a valve body 8 having a. forwardly extending horizontal portion .8

,of'suitable length. Extending longitudi- .nally into-said valve body ;.8 through its portion '8. is a socket 9,'preferably.of slightly tapered form, inv wh'ichis-seated a correspondingly shaped rotatable valve '10 which. has-its outer end'reducejd, forming an an-- nular shoulder 11. A cap nut l2'is threaded upon the outer end of the portion18. of the valve body into seated relation to the shoulder 11 and is adapted for adjustment. to maintain said valve plug 10 against chance rotation.

'- Suita-bly attached "to theopposite sidescof the valve body 8 and commiuiieating with the socket 9 through opposite horizontal ports .13 are the horizontal upper-ends of two substantially L-shaped tubes lldesigned to conduct water-to the interiors ,of the gas igenerating tanks, said tubes having said ends extended through the supports 4 and havingtheir lower ends located centrally of said containers '5 at a suitable height above the bottomslof the latter. .A vertically disposed port 15 leads through; the bottom 1 of t e reservoir and the valve .hody andserves as a passage for conducting water .fromth'e reservoir t ithfl f'sockl'lt 9.. .fIlhe it coincides with-and provides anavenneoi con'miunication between, the port 15 and one or the other of the ports 13 according as the saidvalve plug is rotated forwardorback.

Also attached to the opposite sldes of the valve body forward of the positions ocou-r horizontal gas conducting tubes 17. Said tubes are extended through the supports a and are designed to conduct gas generated Within the tanks to ports 18 leading through the valve body 8 to opposite sides of the socket 9.

The valve plug has a small central bore 19 extending longitudinally therethrough from its front end to a point which, in the seated position of said plug, is adjacent to the ports 18; and leading outward from the inner end of said bore or passage 19 to an arouat peripheral recess 20 provided in said plug is a port 21.

The reduced outer end 10 of the valve plug which, as hereinbefore indicated, also performs the function of a gas conducting tube, may have fitted thereon a separate burner tip of the usual form, or it may itself serve as a burner tip, as shown in Fi 5.

In practice, when the valve plug is turned to the position shown in Fig. 6, water from v the reservoir 1 is supplied to the left hand gas generating tank through the vertical port 15, the left hand horizontal port 13 and the communicating tube 1a, the recess 16 in the valve plug 10 being then in a position permitting communication therethrough between said ports 15 and 13. In said position of the valve, is permitted to feed from said left hand tank to the burner tip, the

recess 20 in the plug 10 being then disposed with a portion thereof in register with the left hand gas port 18, as shown in Fig. 7, and the gas being consequently permitted to pass through the gas tube 17 of said left hand tank, the said port 18, recess 20, port 21 and the passage 19. p I 7 To cut off the supply of gas from the left hand tank and to simultaneously provide for furnishing gas from the right hand tank to the burner, the valve plug is given a partial turn to the right, thereby carrying the recesses 16 and 20 out of register with the left hand ports 13 and 18, respectively, and into register with the right hand ports 13 and 18.

Relief ports 22 of relatively small capacity are provided in the valve plug 10 at points where one or the other thereof, according as gas is being permitted to feed from the right or left hand tank, will register with the port 18 opposite that through which the gas is then feeding, as shown in Fig. 7, the purpose being to permit of the laterally from said collar.

following the shifting of the valve to a reverse position.

A reflector 23 is suitably mounted behmd the burner tip, the same being preferably rigidly mounted, as by soldering, upon the adjustable cap nut 12 so that said nut may be adjusted by rotation of said reflector.

To provide for holding the valve against chance displacement after adjustment thereof, and at the same time to provide means whereby said valve may be shifted or adjusted from one position to another, a collar, as 2%, is fixed upon the reduced end 10 of the plug 10, and a flexible arm 2-5 extends Said arm serves as a lever which may be grasped with the fingers to effectrotation of the valve. A knob 26, or equivalent device, is carried on the outer end of said. arm and normally occupies seated position with respect to one of a plurality of seats or sockets 27 provided at suitable points in the face of the reflector 23, whereby the adjusted position of said valve is yieldingly maintained.
